I had some negotiation problems. But the problems were observed on the other
NIC - bge0. bge0 is connected to the dlink-3627 and bge1 is not always setup
speed/duplex mode correctly. Usually this is solved by link0 setting. Flag
link0 I set for bge1 and bge0. Flag link0 used quite a long time (years).
bge1 and bge0 have link0, when I got the problem on NAS2 first time. Then I
reset link0 and reboot NAS2. After some time I got the same problem again
(current state). However, I do not see any obvious problems with bge0 <-> AT-
x900.
